A review of ZnO nanoparticles as solar photocatalysts ...

Jan 01, 2018· When ZnO is photo-induced by solar light with photonic energy (hv) equal to or greater than the excitation energy (E g), e − from the filled valence band (VB) are promoted to an empty conduction band (CB).This photo-induced process produces electron-hole (e − /h +) pairs as shown in (Eq.). The electron-hole pairs can migrate to the ZnO surface and be involved in redox reactions as …
